[Question] Accessing best_ckpt path

[austinmw]

Hi, how can I access the best saved checkpoint path? I tried:

runner.meta['hook_msgs'].get('best_ckpt', None)

But got the error:

AttributeError: 'Runner' object has no attribute 'meta'

Hi @austinmw , you could use runner.message_hub.get_info('best_ckpt').

If you cannot access runner.message_hub directly, don't worry, it is a globally accessible instance, you can also get best_ckpt by:

MessageHub.get_current_instance().get_info('best_ckpt')

@austinmw Hi! I thought other users might also be interested in this question 😆, and I convert it to a discussion.
